A Study on Fire Factors Analysis Influencing Property Damage by the Use of Fire Extinguishing Equipment in Building and Structure Fires

Although the number of fires has not changed considerably in recent times, property damage and casualties due to fires are increasing every year. Maintaining the performance of fire-fighting facilities installed in buildings has been emphasized for maximizing human safety and minimizing property damage caused by fires. As a result, since 2017, the maintenance of fire extinguishers throughout their service life, has been mandated. In case of a fire, initial fire extinguishing and fire spreading prevention are crucial. There have been no available measures for the maintenance and verification of indoor fire hydrants and outdoor fire hydrant hoses used for extinguishing fires and preventing combustion expansion. This study was therefore intended to present measures for ascertaining the service life of these fire extinguishers, by evaluating their firefighting abilities through sample analysis and case analysis of the fire hoses. Research shows that the degradation of performance of the fire hoses becomes evident between 9 and 10 years, so that 10 years of service life is considered appropriate for the fire hoses.

Uranium Tailings

The uranium tailings is a typical major hazard sources because of its specificity, which could cause serious casualties, property damage and environment pollution in the event of an accident, and thus calls for the attention of everyone. In this paper, we will connect with the practical situation of the uranium tailings, identifying the factors of the dam, such as stability failure of dam slope, overtopping, structure damage, seepage damage and so on. To analyze the related factors and put forward countermeasures based on the analyzed results to control the harmful factors, this will lay the foundation for improving the safety monitoring and security management of uranium tailings impoundment.

The Creation

Fires and accidents at nuclear power facilities that occurred in the past resulted in considerable property damage, both direct and indirect one. The emerging threats had a negative impact on the fire-fighting process that had to be interrupted, which contributed to spreading of fire. One way of solving the problem is to develop and use robotics, and in order to achieve the effectiveness of robotics equipment, this must be designed taking into account the specifics of the facility, where it is planned to be used, and operate throughout the plant premises, while being of the light class. Having analyzed the peculiarities of origination and development of fires at NPPs, as well as taking into account the specifics of the facility, technical requirements for the design of the robotic equipment were developed, which formed the basis for the creation of a prototype implemented in a mobile robotic fire-fighting unit (MRUP). In order to check the stated tactical and technical characteristics, MRUP was subjected to tests for its running performance, operability of its components and assemblies, and fire-extinguishing properties. The test of running performance was carried out on dedicated stands with a variety of inclined surfaces, climbing angles and heights. For MRUP firefighting efficiency to be tested, a model hotspot was extinguished, the range of delivery and the consumption of fire-extinguishing agents were measured.

Human Factors Analysis

Powerful earth moving and other heavy equipment should only move when commanded by the operator. Equipment which may move as a result of the operator contacting one of the controls unintentionally can lead to property damage and bodily injury. This situation can openly occur without the operator realizing it. The general scenarios for unintended control contact are; operator entry / exit from the machine, operator seated but “leans” during distraction, operator seated but stands up and operator reaches through window for controls. The purpose of this paper, though mechanical and human factors analysis, is to inform equipment manufacturers, dealers and machine operators of this hazard. Additionally, it will provide design alternatives and concepts that will assist in mitigating and/or preventing these injuries altogether.

Abstract. The Human Factors Analysis and Classification System (HFACS) methodology was applied to accident reports from three African countries: Kenya, Nigeria, and South Africa. In all, 55 of 72 finalized reports for accidents occurring between 2000 and 2014 were analyzed. In most of the accidents, one or more human factors contributed to the accident. Skill-based errors (56.4%), the physical environment (36.4%), and violations (20%) were the most common causal factors in the accidents. Decision errors comprised 18.2%, while perceptual errors and crew resource management accounted for 10.9%. The results were consistent with previous industry observations: Over 70% of aviation accidents have human factor causes. Adverse weather was seen to be a common secondary casual factor. Changes in flight training and risk management methods may alleviate the high number of accidents in Africa.
